OFFSET

 

Description: This function allows the user to copy and offset a selected line.  The new line    is generated in the UV plane according to a user-specified distance and direction.

 

Usage:

 

1.   DSI prompts:

>      SELECT LINE TO OFFSET

 

2.   Once the desired lines have been selected, DSI prompts:

>      DEFINE PLANE FOR LINE OFFSET

>      PICK NODE/PT FOR ORIGIN

•       The user enters a coordinate system to define the plane in which the line lies. If the line does not lie in the global XY, XZ, or YZ plane, then the user selects three points on the line to define the plane.  A thorough explanation of how to create a local coordinate system is covered in Local Coordinate System, Section 2.16.

 

3.   Once the desired coordinate system is acquired, it will be displayed on the screen, and the prompt will read:

>      ACCEPT? (YES/NO)

 

4.   If the user selects YES, then DSI prompts:

>      ENTER OFFSET DISTANCE IN UV PLANE OR -1 TO EXIT

•       The user enters a positive distance and an arrow appears at the beginning of the line.

 

5.   DSI prompts:

>      ACCEPT OFFSET DIRECTION? (YES/NO)

 •      YES creates a line in the displayed direction at the specified distance.

 •      NO creates a line opposite the displayed direction at the specified distance.
